Use the DCC to inject a signal directly
(via electrical contact) into the target line Advantage: better than
using inductive mode for assuring
that target line is only thing
energized Also eliminates air
coupled signals that come from the
transmitter case itself Disadvantage:
part of line must be electrically
exposed to use the DCC which
sometimes is impractical Also
requires adequate ground return to
cause strong signal on line

This simple accessory can be used to
establish good grounding for direct connection to
a line Advantage: establishes better ground
return when used than when not used
Disadvantage: must have penetrable terrain to
use it

This is the non contact version of the DCC Use
the Inductive Clamp to energize the target line by plugging into a Model
X direct output jack and clamping around a portion of the line
Advantages: no electrical contact
point needed; very effective at
energizing the target line only
even in congested areas
Disadvantages: part of line must
be mechanically exposed enough
to get clamp around it; limited
target line diameter (up to about
” OD)

These are small capsule type transmitters that
may be located only in the immediate area surrounding the transmitter
They are usually inserted inside non metallic lines in order to pinpoint a
location in the line but can be used for a variety of applications
Typically transmitting sondes are battery operated and water tight
(a) The
Model
“Flusher”
is a
watertight capsule transmitter
designed specifically to be flushed
down a toilet or a sewer cleanout They
are most often used for locating septic
tanks
